The power battery will generate a lot of heat during the rapid charging and discharging process, which will cause the temperature of the battery to rise. If the temperature of the battery pack is too high or the temperature difference is too large, it will cause a series of safety hazards and seriously affect the work of the battery pack.

Hybrid cooling is mainly composed of two or more of the first three cooling strategies. Among the first three cooling methods, the cooling effect of liquid cooling is more obvious. At present, there are many researches on liquid cooling. The battery thermal management system of liquid cooling combined with other cooling strategies is also relatively common, but it is far from the hybrid cooling method based on liquid cooling. Applying it in practice still needs more in-depth research.

现有的电池热管理系统中，电池的换热面积有限，多个电池形成的电池组工作时换热效率较差，且不同部分的电池温度相差较大，导致电池的寿命和使用性能受到影响，温度过高时还会有着火的风险，因此有必要提供一种换热面积大、换热效率高且电池组温度分布均匀的卷曲型液冷电池热管理系统。In the existing battery thermal management system, the heat exchange area of the battery is limited, and the heat exchange efficiency of the battery pack formed by multiple batteries is poor during operation, and the temperature of different parts of the battery varies greatly, which affects the life and performance of the battery , There will be a risk of fire when the temperature is too high, so it is necessary to provide a coiled liquid-cooled battery thermal management system with a large heat transfer area, high heat transfer efficiency and uniform temperature distribution of the battery pack.
